PLOW.

SPECIFICATION formingpart of Letters Patent No. 255,283, dated March 21, 1882.

- Application filed February 25, 18:32. (No model.)

Toall whom it may concern Be it known that I, MILTON TAYLOR HAN- COCK, a citizen of the United States, residing at Thomasville, in the county of Thomas and State of Georgia, have invented new and useful Improvements in Plows, of which the following is aspecification.

The object ofmy improvementsis to afford facilities for adjusting the mold-board and the land-bar independentlyofeach other in respect to their position on the beam-standard to compensate forthe wearlof the mold-board and to give an easy run to the plow, to provide means for adjusting the handles, both as to height and width, to suit a man or boy, and to provide for bracing the handles in connection with the means by which they are adjusted.

Referring to the accompanying drawings,

. Figure lrepresents myimproved plow, looking at the landside with the handles set low; Fig. 2, an elevation with the handles set high; Fig. 3, a top view; Fig. 4, a rear view; Figs. 5 and 6, the beam-standard and laudside, with the mold-board removed to show the box-plate upon which it is secured and adjusted; Fig. 7, the bent screw clamping and supporting rod, and

Fig. 8 the mold-board side of the plow.

The beam has the usual curved standard, to which the mold-board a. and the land-bar b are secured. A box-plate, c, secured to the inner side of the standard, is formed with an open box projection, 07, so as to form a support for the mold-board and to receive the bolt by which it is secured upon the standard. For this pur- 3 5 /pose the box projects from the inner side of the standard a sufficient distance to form a seat flush with the front edge of the standard, and the bolt 6, which secures the mold-board, passes through it and the box and is bound by a nut,

40 f, clamped against the under open end of the box. The box-opening is oblong, one side being forined by the beam-standard, so that as the front edge of the mold-board wears the bolt is loosened and the mold-board set down. The 5 land-bar is also set down to bring its lower edge on a level with the mold-board front, and for this purpose the land-bar is provided with slots 9 g, through which its securing-bolts it pass into the standard, and these bolts serve 50 also to secure the open box to the standard.

This construction adapts the land-bar to a long and a short mold-board, and the adjustment of both or either, as may be required to keep them on a level to give the plow a smooth run. The handlesj are secured to the beam by the bolt k and by a rod, 1, bent over the handles in a peculiar manner, and combined with a right-andlet't-screw-threaded nut and cross-brace for the purpose of adapting the handles to be set high or low and nearer to or farther from each other, as may be required for use by a man or by a boy in plowing. This rod is of wrought-iron, and is passed through a holein the standard at a point about where its curve terminates in the beam. At this point the rod is pinched in or bent over the top edge of the beam and bound by a clasp or tie-link, n, so as to tie and brace it'to the beam. The ends of the rod are then bent and passed through slots 1" in the handles from their inner sides over their outer sides and top,

and united by a right-and-left screw nut, s, be-

tween the handles. A cross-brace, t, spans the space between the handles, and is tenoned into their slots, so that theyare bound against the shoulders to of the tenons c by the rod which ties said handles together. The crossbrace t is not fixed to the handles, but can be moved in its slots in setting the handles high or low. In this adjustment the handles turn upon their beam-connection, and the bent rod turns upon its beam-connection, and as the handles are raised or lowered the bent rod will follow down or up in the slots of the handles; but to allow of this adjustment of the handles the right-and-left screw nut must be first turned to release the binding and tying action of the rod upon the handles. When the handles are adjusted low they are caused by said setting to be brought nearer together to suit a boy or a short man, and when the handles are set high they are caused by said setting to be opened wider to suit a tall plowman. When the bandles are so adjusted they are bound together upon the cross-brace by the screw-threaded nut into which the two ends of the rod are I will cause them to'spread, because the handles are joined at their beam-connection, and in setting the handles low the outside bends, 11 5 of the rod will act against the outer sides of the handles to draw them together. The rod, the handles, and the cross-brace make a very firm frame by which to handle the pl0w,while giving the advantage of adapting the handles for being set h gh or low for the purpose stated.

The plow shown is adapted for breaking up the earth; butthe mold-board and the land-bar may be removed and a scraper or cultivatorshare secured upon the open box for cultivating growing plants.

I claim- 1. The combination, with the curved beam-- standard and the adjustable mold-board a, of the open box-plate c, the adjustable land-bar b, the screw-bolts, and their confining-nuts, the said box-plate and land-bar being secured to V opposite sides of the standard by the screwscrew-threaded rod 1, bound and tied to the beam and passed through said handle-slots, the right-and-let't-screw nut s, and the shouldered cross-brace t, arranged within the said handleslots, whereby the handles are adapted for vertical adjustment, and braced and supported vertically and laterally, substantially as herein set forth.

3. The combination, with the beam, of the handles having the slots 1'1, the screw-threaded rod 1, the clasp or link a, and the right-andleft'screw nut s, the said rod being passed through the handle-slots and having the inner and outer bends, 2" i on opposite sides of said handles, and united above the latter by the said screw-nut, whereby the handles are adapted to be set high or low, and to vary the distancebetween the handles to suit a. high or low position thereof, substantially as described.

In testimony whereofI havehereunto set my hand in the presence of two subscribing wit.-

nesses.
